SPECIFICATION forming part of Letters Patent N0. 775,921, dated November29, 1904.

App ication filed July 15, 1904a Serial No. 216,642. (No modeLi To all1072,0711, it Duty concern:

Be it known that I, HENRY M. HILn, a citizen of the United States, and aresident of Canton, in the county of Stark and State of Ohio, haveinvented certain new and usefulImprovcments in Telephone-Call Tellers;and I do hereby declare that the following is a full, clear, and exactdescription of the same.

The object of the present invention is to provide a device by which thename and number of a telephone subscriber can be brought to view for thepurpose of calling the central operator.

In the accompanying drawings, Figure 1 is a front view showing one ofthe indicator plates or blades partially turned into View. Fig. 2 is aview showing a portion of one of the indicator-blades and manner ofattaching same to the operating and retaining device. Fig. 3 is a viewshowing my improvement properly attached to a telephone. Fig. 4 is adetached view of one of the blade-holding devices, showing the bladepartly broken away. Fig. 5 is a vertical section of the shell orhousing. Fig. 6 is a perspective view showing the different partsproperly arranged and the same detached from the telephone.

Similar numerals of reference indicate corresponding parts in all thefigures of the drai ings.

1n the accompanyingdrawings, 1 represents the back or fixed member ofthe shell or housing, and 2 represents the front section or member ofthe housing. Said members 1 and 2 when brought into proper relativeposition are located with reference to each other substantially as shownin Figs. 1, 3, 5, and 6.

The fixed section or member 1 is provided with the integral annularflange or hub 3, which is formed hollow, as illustrated in the drawings,and at the back or rear portion of said flange are located theconnecting-wires 1, which connecting-wires are formed of spring materialand are so formed for the purpose of fitting upon the screw-threadedends of the transmitter 5, which transmitter is of the usualconstruction and forms no particular part of the present inventionexcept that the transmitter is used to provide a means for clamping myimproved device between the diaphragm-hcad 6 and said transmitter,substantially as illustrated in Fig.

The shell or housing2 is provided with the hub or flange 7, which hub orflange is connected to the flange or hub 3 of the fixed housing member1.

For the purpose of securely connecting the flange or hub 21 and theflange or hub 7 together theflangc 3 is provided with the curved slotSand the hub 7 provided. with the head or knob 9, which head or knob ispassed into the open end of the slot 8 and the housing 2 rotated, whichmoves the head 9 in the slot 8, thereby connecting the two hubstogether.

For the purpose of preventing any springing movement or opening of theslot 8 the flange or hub 23 is provided with the bent connected portion10.

The housing or member 2 is provided with the inward-extending flange 11,which inward-extending flange provided with the curved slot 12, whichcurved slot receives the head 13, which head is formed upon the member1, by which arrangement the two sections or members are so connectedthat there will be no relative movement between said members, and at thesame time they can be easily detached from each other.

For the purpose hereinafter described the index-blades lat arepreferably formed semi circular and preferably of celluloid; but I donot desire to be confined to any particular kind of material. To theplates 1a are attached the rods 15 by means of suitable clips 16.

The rods 15 are provided with the semiannular portions 17 and the blades14 with the semicircular recesses 18, by which arrangement a circularopening is provided, which opening is for the purpose of receiving thehub 7, or, in other words, for providing a means for placing any desirednumber of plates l h'togcther with the part attached thereto, upon thehub 7.

In use it is desirable to have the same number of plates that there areletters in the alphabet, or substantially so, and each rod 15 providedwith a letter-disk 19, and for the purpose of bringing the differentletters of the alphabet to view the rods 15 increase in length fromfront to rear, as illustrated in Fig.

In assembling; the different blades 14, together with theiroperating-rods, it is desirable to have the letters upon the letter-diskcorrespond with the first letter of the name of the subscriber, thisfeature being illustrated in Fig. 1, and by the use of the letter H, bywhich arrangement when the rod 15, provided with the letter-disk H, isturned to the right and downward it will expose to View the blade havingthe subscribers names beginning with H, by which arrangement anyalphabetical list ofnames may be brought to view.

For the purpose of preventing one blade from following another the hub 7is provided with the rib 20 and the curved portion 17 of the rod 15 isprovided with the notch 21, which notch 21 receives the rib 20, asillustrated in Fig. 2, when the various rods 15 are brought intovertical position. (Illustrated in Fig. 1.)

It will be understood that the rib 20 and the notch 21 should be soformed that a slight pressure upon any rod 15 will disengage the notchfrom the rib.

The member 1 of the housing is provided with the shoulders 22 and 23,which shoulders are preferably located diametrically opposite eachother, so that each of the blades 14, together with their differentattachments, can be given a half-turn, by which movement the blades 14are exposed or located side by side and back of the front blade of thehousing member 2.

hen it is desired to remove any particular blade or to add new bladesfrom time to time, the front member 2 is removed, together with thedifferent blades and their attachments, after which they can be detachedand rearranged or new blades provided.

For the purpose of providing a means for turning the diiferent rods 15,the letter-disks 19 or the rods, as the case may be, are provided withthe angled nibs 24, and by locating the same at an angle they can bereached by the finger without disturbing or interfering with any of therods except the onedesired to be turned.

The object and purpose of forming the wires 4 of yielding or springmaterial is to provide a means for attaching the device totransmitter-tubes of different sizes or of different diam'eters.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is,

1. In a device of the class described, a telephone-transmitter tube, ahousing formed of detachable members, one of the members secured to saidtelephone-transmitter tube and the other detachably, connected thereto,hubs formed upon the housing members, and one located within the other,index-blades provided with operating-rods, and the rods provided withletter-disks, substantially as and for the purpose specified.

2. In a device of the class described, a telephone-transmitter, ahousing secured to said telephonetransmitter, said housing havinglocated therein, a series of index-blades adapted to rotate, and rodsconnected to the blades, said rods formed of different lengths andprovided with letter-disks, substantially as and for the purposespecified.

3. In adevice of the class described, a housing formed in sections, andhubs, one of the sections provided with an attaching wire formed ofspring metal adapted to be connected to a telephone transmitter, andindexblades located within the housing, and said index-blades providedwith rods having letter-disks and nibs, substantially as and for thepurpose specified.

4. In a device of the class described, a housing having located thereina series of indexblades arranged alphabetically, said blades providedwith bars and the bars consisting of extended portions and curvedportions, the curved portions provided with recesses, a retaining hub orflange provided with a rib adapted to engage the recesses of the curvedportions of the blade operating bars, substantially as and for thepurpose specified.

5. In a device of the class described, a transmitter-tube, ahousinghaving located therein a series or index-blades, said bladeslocated concentrically with the transmitter-tube and the blades providedwith rods having letterdisks, substantially as and for the purposespecified.

6. In a device of the class described, a transmitter-tube, a housingformed in sections and the sections detachably connected together, andone of said sections provided with stopshoulders located substantiallydiametrically opposite each other, a series of rods adapted to strikeagainst the shoulders, said rods having connected thereto index-blades,and the index-blades rotatable around the transmittertube, and means fortemporarily holding the blades against rotation, substantially as andfor the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

HENRY M. HILE.
